In this article, we will compare different energy storage system in terms of their advantages & limitations. The comparison is given in the table.
| S.No. | Energy Storage System | Advantages | Limitations |
| 1 | Li-ion battery | 1. It has a high specific energy
2. Light Weight 3. High Cycle life |
1. Costly
2. Need Battery Management System 3. No establishes system for recycling |
| 2 | Flywheel | 1. Longer lives than battery
2. No degradation of power 3. Non-inflammable 4. No daily cycling limitations 5. Full power over full SOC range |
1. A danger of explosive shattering of the massive wheel due to overload, thus safety concerns. |
| 3 | Fuel Cell | 1. Water is the only discharge | 1.CO2 discharged with methanol reform
2. Technology currently expensive 3. Pure hydrogen is difficult to handle |
| 4 | Ultracapacitor | 1.Comparatively quick response time.
2. specific power of 1000–2000 W/kg with 95% energy efficiency. 3. longest lifetime of almost 40 years |
1. High self-discharge
2. High cost 3. Low energy density |
